The Three Processors

An exceptional laptop processor is a key point to an exceptional laptop. A laptop processor acts as a PC’s brain, so to speak. Three Intel laptop processors are the Core i3, Core i5, and Core i7. They each have different qualities and would benefit the user in different and similar ways. Comparing and understanding these qualities are necessary to deciding on which laptop you would like to buy.

Amount of Cores

The Core i3 Laptop processor is the oldest model of laptop processors. It is a dual-core processor and can, therefore, perform the least number of functions at a time out of the three. All Core i5 processors but one are quad processors. Core i7 processors have 4-8 cores. The issue with many cores is that many applications aren’t able to use them, so the performance doesn’t have too much of a difference.

Intel Hyper-Threading

Usually, a core can perform only one thread, or function, at a time. Intel, though, has a technology called Hyper-Threading, in which multiple threads can be performed by only one core. i3 core processors support this technology. These processors have two cores, but Hyper-Threading allows 4 threads to be performed at the same time, making the processor be able to perform about the same amount of threads as an i5, which does not support Hyper-Threading. Core i7 processors support Hyper-Threading, which means it can perform a maximum of sixteen threads at one time, because the maximum number of cores in an i7 is 8. If you tend to have to do many things at once on your PC, and i7 might be more ideal.

Intel Turbo Boost

Intel turbo Boost is a technology that allows a laptop processor to have a faster clock speed when needed. The maximum amount Turbo Boost can raise clock speed is based on the number of cores in active use, estimated current/power use, and the temperature of the processor. Turbo Boost is only available on the i5 and i7, as they are later models.

Cache Size

If a CPU uses the same data many times, the data will get stored in its cache. This is a faster RAM, because it’s actually built into the CPU. RAM and cache are places used for holding data, so it would be important to have large quantities of both. Fourth Generation Core i3 processors have 3 to 4 MB of cache data. Fourth Generation i5 processors have 4 to 6 MB, and finally, all Core i7 CPUs contain 8 MB of cache data. This is a key reason the i7 is superior to i5 and i3 processors.

Your Choice

All in all, the Core i3, i5, and i7 processors are three options in the world of computing. Ultimately, the choice is yours on which one you would prefer. Take into thought the number of cores, the cache size, and the extra boosts the processors have each in turn. Each processor has different qualities, and you can take your pick. If you plan on running older/retro type games, look into the i3 and for those running more intense games, look into the i5 and i7.
